Deep Discharge Lockout (DDLO)
PMU will enter the deep discharge lockout (DDLO) state when the battery voltage falls below 2.5V. In this state,
the VRTC LDO will be shutdown.
Reset
The PMU contains a reset control circuit which will take effects at both power-up and power-down. The “RESETB”
pin is held low in the beginning of the power-up and returns high after the pre-determined delay time. At
power-off, the “RESETB” pin will return low immediately without any delay.
